Width cutoff?

I’ve heard of the VST plugin called VoiceTrap, but it has such a narrow isolation width.

My goal here, is to cut off the guitar from some hard rock songs (which in these cases, have the guitar panned off to the far left and far right)… so I know what I want to do, I’m just physically unable to do it at this point.

Does anyone know of a plugin like VoiceTrap, that will allow me to cut out a wider area, so that I can have the song with the outer edges cut out?

VoiceTrap was a recent discovery by this forum about six or so months back. Before that, you couldn’t do this task at all.
This is another one.
